Problem while backup


I have the next problems while i am making a backup in Tamino on WNT:

- If i click on the database i am backing up, it shows:

I555(E): SQL statement failed with internal error 336.

- If i click on properties i see the default properties, but they are not the database properties.

When backup finish, i see all correctly.

Is this normal? Can this be cause of other problems?

Thanks and regards.
